Z = -b - a + 1
subtract 1
1z - 1 = -1b - 1a ( 1z is the same as z, same goes for b and a)
add -1b
1b - 1z - 1 = -1a
then we remove -1 by dividing it.
-1b -(-1z) + 1
Answer: -1b -(-1z) + 1 = A
A negative minus a negative is a positive, so the answer might as well be....
-1b + 1z + 1 = A
Answer:
77bb
Step-by-step explanation:
a) ∠CEA and ∠DEB are reflections of each other across point E, the intersection point of lines CD and AB. They are vertical angles.
b) ∠AED and ∠BED together form a straight line, so are a linear pair. That means they are adjacent and supplementary.
The sum of the question is 5.
Answer: (-2,2)
Step-by-step explanation:
3x-4y=-14
2(3x+2y=-2)
3x-4y=-14
6x+4y=-4
9x=-18
x=-2
3(-2)-4y=-14
-6-4y=-14
-4y=-8
y=2
